Question

Lattice enthalpy and enthalpy of solution of NaCl are 788 kJmol - 1 and 4 k J m o l - 1 , respectively. The hydration enthalpy of N a C l is:, - 780 kJmol - 1, 780 kJmol - 1, - 784 kJmol - 1, 784 kJmol - 1

MARKS App · Accepted Answer

Enthalpy of solution= Lattice enthalpy + enthalpy of hydration 4 = 788 + ∆ H hydration ⇒ ∆ H hydration = - 784 KJ / mol
